<p>Let us define a typical web application as being a set of:</p>
<blockquote>
<ol class="arabic simple">
<li>Users - who use the application</li>
<li>Roles - roles assigned to users for various functions</li>
<li>Pages - where users navigate and see relevant information</li>
<li>Forms - where users enter new data</li>
<li>Reports - where users get a tabulated view of their data</li>
<li>Permission Rules - that define what each role is allowed to do or not do</li>
<li>Logic - Automatic actions that are performed at various events</li>
<li>Validations - Checks that ensure the data entered by the users is valid</li>
<li>Print Formats - Printable documents based on the data users have entered</li>
<li>UI Widgets - Menus, Lists, Dialogs that are used for navigating, entering or displaying information</li>
<li>Module - So that you can group Roles, Forms, Pages, Reports for more complex applications</li>
</ol>
</blockquote>
<p>Let us now start building these entities in the wnframework</p>
